Hello Everyone

Some welcome rain, 40mm, here since Wednesday. It has been dry and dusty
from early December. There was decent fall of hail last night so would
expect a reasonable amount of snow above 800m.
7am temperature 8C.

Most of you on the list can say why you have thunderstorms.
Does anyone have thoughts (the big picture) on why Tasmania does not
have many?

Chas

Great picture of a microburst, with 40C the evaporation would aid this. The
lightning pictures are also very good. Better than anything I have seen this
season.

 Hi all,

 Just found an interesting site on the NOAA's hurricane hunter aircraft....some cool photos and interesting info!
 Maybe a bit off topic, but cool nonetheless!

Most mid to high latitude small Islands get very little storm activity,
although it varies. ( I think Britain probably outdoes Tasmania ). Lack of a
continental landmass and subsequent heating is one of many reasons. The
frequency would vary somewhat in Tasmania too. Worse than you the lower
Derwent River valley is probably the least thunderstorm prone area in
Australia. The mountains would get more storms than you.

Those that read my annoying posts in the past will recall that I have said a
few times now that NGAPS always seems to go for the ' big play '. During
winter it torments us SE coast people with East Coast lows, most of which
never eventuate.

Is there any reason why NGAPS does this, is it something military - as in
wanting to know the worse possible outcomes for their warships, so that they
are prepared.

The cloud band you talk about was visible on the sat' pic. It was a thin streak, almost frontal looking on the pic ( although obviously different at surface ). It went offshore between Nowra and Batemans Bay.
 
I was a tad disappointed in the violent planet episode tonight, I had made a lovely cup of tea and settled down to enjoy it, I became bored towards the end of the show, in fact I enjoyed The Bill much better, rare for me.

Subject: aus-wx: Storm program on ABC TV at 7.30 tonight

Just a reminder that the ABC TV's This Violent Planet series is featuring storms tonight at 7.30pm.
 
There should be some good shots of tornadoes, cyclones, mid-latitude storms etc.
 
Just the tonic for those of us who haven't seen a storm for a couple of months (mid-late this coming week may offer something for SE Aust?)
 
Some nice cloud effects over Canberra with the jet stream overhead this morning. Cirrus of all kinds (cirrostratus, cirrocumulus and just plain cirrus) moved rapidly across the sky constantly changing shape as they did. Just a pity the lower atmosphere wasn't a little more like Brisbane's.

Have zoomed in on and animated the activity around Brisbane and Perth - very interesting.. In relation to the jet stream cloud, I agree with you it does look a lot like a front moving up the NSW coast. Following the animation sequence as the band moves up the coast and then out into the Tasman it eventually seems to interact with a much more favourable surface and mid-level environment kicking up a very nice and large looking cell by 2225UTC about 400-500km east of Coffs Harbour. A very interesting process to watch. Patrick The cloud band you talk about was visible on the sat' pic.

Compared to the Oklahoma tornado program, this one was pretty light on. Many contrived images (ie the waterspout where disturbed water was shown but no image of actual funnel; coral reef shots seemingly taken during the hurricane -who in their right mind would be out diving - let alone with film equipment during a hurricane??) which at least they admitted to at the end. I know that on prime time TV you will never get any level of technical commentary that would satisfy many on this list. I do have higher expectations of at least seeing some nice footage given that TV stations have access to reasonable $$$. Mind you the Oklahoma tornado program has set a very high standard which realistically is unlikely to be often repeated.

Certainly this was very active, and this doesn't include the other storms to its north! The tracker only picks up CG's...interestingly, most of the strikes in this area (sunshine coast & wide bay & burnett districts), are often quite high. But the area is very hilly/mountainous - so this may have something to do with the high freqeuncy of CG's.

Our next QLD ASWA meeting will be held at 10am, Saturday the 5th of February. We did not have a January meeting as many people were away on holidays. Our last official meeting was November of 1999 (with a Christmas BBQ taking place in December). It would be great if you would be able to attend this meeting. We have organised a guest speaker, Jeff Callaghan head of severe weather at the Bureau of Meteorology has agreed to give a talk on: - Tropical Cyclones; - Forecasting Tropical Cyclones; - Periods of which Tropical Cyclones tend to occur in (eg, MJO's, El Nino etc); - Correlation between El Nino/La Nina vs TC's vs Thunderstorms. We also plan to have an important discussion on the possible implementation of a Queensland ASWA lightning tracker, similar to that displayed on the Energex homepage, but a real-time version. Everyone's input and ideas would greatly be appreciated for this! Anthony Spierings (an ASWA member/ Energex employee), will currently be attending this meeting to assist in the discussion. We have other various items on the agenda, which include possible weather education seminars later on this year, which may again be held in conjunction with the BoM. There is currently plenty of video footage, with the Nov 22, 1999 Condamine F0 tornado on tape, and many hours of further footage (not all of this will be shown of course!) Any other footage that is taken in the next two weeks before the meeting may also been shown. The address is: Unit 9/14 Argon St. Sumner Please bring $2 for a light lunch after the meeting. I look forward to seeing you there, please inform me if you are able to attend.

In relation to SE Aust, it has the active part of the current trough over WA slipping southeast and brushing past Adelaide and Melbourne before intensifying and giving some very heavy rain across parts of NSW before focusing rain on the central and south NSW coast (and E Gippsland). Possibly setting up for a deep low just of the SE corner late in the weekend (I notice MRF going for a very deep SE coast low and cold outbreak on the following Monday 31 Jan - but that is out in fantasy land at 8 days out). Will be interesting to watch. Paul in Darwin has indicated how he is being teased by a low brushing across the top end. The other interesting aspect of the last couple of runs has been the tropical low it has moving SE from the central Indian Ocean. It first appears at 84 hrs, at 144hrs it has kept it moving SE and presumably will be entering latitudes where the steering winds are likely to keep it moving SE. Would be an interesting scenario for WA west coast (possibly even Perth) if it maintained its identity and direction. MRF picks up the low as well but kills it off well away from the coast - presumably at least in part a function of colder surface waters). Most of the above is pretty speculative but as things are pretty quiet storm wise in Canberra at the moment, one can only hope...

The most intense thunderstorms occur when hot/humid continental air in the lower/middle layers is de-stablilised by a strong jetstream or up-motion in the upper atmosphere. Tasmania gets the jets, but being a relatively small landmass surrounded by a cool ocean means that the lower atmosphere never gets a chance to become hot and humid. Most thunderstorms form near the jet or approaching front but lack the moisture to be as powerful as mainland storms. Storms can form on the NE ranges in a slow moving trough after a few days of N winds from the mainland, but they will rarely be as strong or as frequent as similar storms that form on the Victorian ranges. Wed/Thu may see a situation resulting in thunderstorms across Tasmania. However, as it often the case, low level cooling due to the maritime influence may result in more rain than thunder.

LOL!!! It's a shame we don't have more people chasing storms in the SE Quarter of QLD - the guster shots i took of the first storm yesterday were taken when the storm was weakening, and was yellow on radar at the time i took the shots - i would have loved to have photographed the guster when the storm was pink and red on radar.. but if people have other commitments i guess that's just the way it is.. > > > > Just spoke to someone at Energex, and northern SE QLD and eastern Wide > > Bay Burnett have copped a hiding.. with up to 30 suburbs without power > > at the time i called (would have been higher this afternoon i guess) - > > he couldn't give me an exact number of clients without power like they > > sometimes do, but my guess 50 000 or more? > > Specifics usually get cleared through Public Affairs first.

I think it would have been smoke - i went back up the coast today for a swim and to photograph the Glasshouse mountains.. and there was a large area of burnt bush land near Glass House township, and several other smaller grass fires around.. +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from aussie-weather send e-mail to:majordomo at world.std.com with "unsubscribe aussie-weather your_email_address" in the body of your message. -----------------------jacob at iinet.net.au------------------------------
